A two-and-a-half hour meeting between staff representatives and employers ended in stalemate with no agreement being reached.

Workers therefore voted to take strike action which will affect airports and hospitals and could once again produce mountains of rubbish during the busiest and hottest time of the year.

When cleaners went on strike in 2017, British holidaymakers described the conditions at the airport as "filthy," with overflowing litter bins containing everything from dirty nappies to discarded food.

One angry passenger said: "You have to wade through it. It’s definitely not what you’d expect to see when coming home from holiday. I’ve been to many airports and never seen anything like that.”

The Workers’ Commissions union slammed an offer of a six per cent pay rise as "puny" and said the employers refused to budget.

That six per cent would have been payable over a period of five years plus a further one per cent on further conditions.

The union says its demand is "much more ambitious" and wants nothing less than 25 per cent payable over the next four years.

A rep said: "Although at first glance this might seem preposterous, we think it is only fair when you take into account that, in the last four years, the salary of the workers has only increased by a meagre 0.5 per cent in 2016 and 0.5 per cent in 2017."
